Frequently Asked Questions - TE-5.5-MDQ-SC Little Giant

How to install the Little Giant TE-5.5-MDQ-SC pump?

Install the pump in a well-ventilated area, protected from splashes, and make sure the suction volute is below the liquid level for priming. Secure it firmly to avoid vibrations and do not support it solely by the discharge pipe.

Can I use this pump outdoors?

No, the pump is not designed for outdoor use. It must be installed protected from the weather and below freezing temperatures, as frost can damage the unit.

What to do if the pump does not start?

First check the power supply and grounding. Make sure the pump is properly primed and that the impeller is not blocked by debris. If the problem persists, unplug it and contact an authorized service center.

How to clean the pump impeller?

Unplug the pump, remove the 4 wing nuts from the housing, then gently disassemble the impeller. Clean it with a soft brush to remove debris or corrosion. Reassemble carefully.

What type of oil to use for lubrication?

Use a SAE 20 non-abrasive oil (no additives). Pour 2-3 drops into the lubrication holes located on top of the motor, at each end, every 6 months.

Is the TE-5.5-MDQ-SC pump submersible?

No, this pump is not submersible. It must operate in the open air and should never be immersed. Install it in a dry, well-ventilated location.

What electrical voltage is required?

The pump operates on 120 V with a grounded three-prong plug. Plug it into a properly grounded outlet in compliance with electrical codes.

Can I pump saltwater with this pump?

The pump is designed for fresh water, light oils, and non-corrosive liquids at room temperature. For saltwater, check material compatibility; prolonged use may accelerate corrosion.

What to do in case of water leak?

Check that the wing nuts are tightened and that the nitrile O-rings are in good condition. Replace seals if necessary. If the leak persists, contact a service center.

How to store the pump in winter?

Drain all water from the pump and pipes. Clean it and dry it thoroughly. Store it in a frost-free location to avoid cracks or deformation from freezing. Follow cleaning guidelines before storage.

DESCRIPTION

This is a magnetic drive pump intended to move water through aquarium filtration systems. The pump should be installed external to the aquarium and filtration systems, and is usually mounted below the aquarium in the cabinet that houses the filtration systems. The pump head parts are made of glass filled polypropylene. The spindle shaft and thrust washers are ceramic. The impeller driven magnet is coated ceramagnet A (barium ferrite) type ceramic. O-ring seals are nitrile. The motor is thermally protected.

SAFETY GUIDELINES

WARNING

DANGER: To avoid possible electric shock, special care should be taken in the use of aquarium equipment. For each of the following situations, do not attempt repairs yourself; return the appliance to an authorized service facility for service or discard the pump.

1. Do not handle the pump with wet hands or when standing on a wet or damp surface or in water.
2. If the appliance falls into the water, DO NOT reach for it! First unplug it and then retrieve it. If electrical components of the appliance get wet, unplug the appliance immediately. (nonimmersible equipment only)
3. Carefully examine the appliance after installation. It should not be plugged in if there is water on parts not intended to be wet.
4. Do not operate the pump if it has a damaged cord or plug, or if it is malfunctioning or if it is dropped or damaged in any manner.
5. To avoid the possibility of the pump plug or receptacle getting wet, position aquarium stand and tank to one side of a wall-mounted receptacle to prevent water from dripping onto the receptacle or plug. Arrange a drip loop for each cord connecting an aquarium pump to a receptacle (Figure 1). The drip loop is that part of the cord below the level of the receptacle (or the connector if an extension cord is used) that prevents water from traveling along the cord and coming in contact with the receptacle. If the plug or receptacle does get wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the pump. Then unplug and examine for presence of water in the receptacle.
6. Close supervision is necessary when any pump is used by or near children.
7. Always unplug the pump from the outlet when not in use, before putting on or taking off parts, and before cleaning. Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.
8. Do not use the pump for other than intended use.
9. Do not install or store the pump where it will be exposed to the weather or to temperatures below freezing.

1. Make sure the pump is securely installed before operating it.
2. Read and observe all the important notices on the pump.
3. If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the pump rating may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
4. DO NOT USE TO PUMP FLAMMABLE OR EXPLOSIVE FLUIDS SUCH AS GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT USE IN EXPLOSIVE ATMOSPHERES. PUMP SHOULD ONLY BE USED WITH LIQUIDS COMPATIBLE WITH PUMP COMPONENT MATERIALS.
5. IN ANY INSTALLATIONS WHERE PROPERTY DAMAGE AND/OR PERSONAL INJURY MIGHT RESULT FROM AN INOPERATIVE OR LEAKING PUMP DUE TO POWER OUTAGES, DISCHARGE LINE BLOCKAGE, OR ANY OTHER REASON, BACKUP SYSTEM(S) AND/OR ALARM SHOULD BE USED.
6. THIS PUMP IS SUPPLIED WITH A GROUNDING CONDUCTOR AND/OR GROUNDING TYPE ATTACHMENT PLUG. TO REDUCE THE RISK OF ELECTRICAL SHOCK, BE CERTAIN THAT IT IS CONNECTED TO A PROPERLY GROUNDED GROUNDING-TYPE RECEPTACLE.
7. SUPPORT PUMP AND PIPING WHEN ASSEMBLING AND WHEN INSTALLED. FAILURE TO DO SO MAY CAUSE PIPING TO BREAK, PUMP TO FAIL, MOTOR BEARING FAILURES, ETC.

ELECTRICAL CONNECTIONS

WARNING

Check the pump label for proper voltage required. Do not connect to voltage other than that shown.

GROUNDING INSTRUCTIONS: This appliance should be grounded to minimize the possibility of electric shock. This appliance is equipped with an electric cord having an equipment grounding conductor and a grounding-type plug. The plug must be plugged into an outlet that is installed and grounded in accordance with all appropriate codes and ordinances. This appliance is for use on a normal 120 volt circuit, and has a grounding plug that looks like the plug illustrated in Figure 2. This pump should not be used with a three to two grounding adaptor.

OPERATION

1. The pump is supplied completely preassembled and pretested from the factory. Make sure the nuts (Figure 3, item 13) are tight before operating the pump.
2. Use a thread sealer on all pipe connections and hand-tighten only.
3. The pump is not self-priming. It must be operated with the volute intake below the liquid level.

GROUNDING PIN EPINGLE QUI METTRE A TERRE MOLIO ALFILER

Figure 2 • Figure 2 • Figura 2

1. This pump is not submersible. Operate the pump only in the in-line mode. DO NOT put the pump in liquid. Pump should be located in a well ventilated area and away from where accidental water spillage would cause wetting of the pump.
2. The weight of the pump must be supported adequately. DO NOT support the pump by the intake and discharge connections alone.
3. Do not allow the pump to run dry (without liquid). Heat buildup caused by friction will damage the pump parts when dry.
4. Do not attempt to restrict the intake side of these pumps. Restricting the intake may cause damage to the pump head. If you require reduced flow rates, then place a valve on the discharge side of the pump or if flexible vinyl tubing is used, a clamp can be used on the tubing to restrict the flow.
5. If the pump is to be idle for a period of time, follow the cleaning instructions outlined in the next section. Do not let the pump freeze in the wintertime. This may cause cracking or distortion that may destroy the pump.

AQUARIUM APPLICATIONS

When using this pump for aquarium filter applications, refer to the instructions and owner's manual supplied by the filter manufacturer.

SERVICE INSTRUCTIONS

WARNING

MAKE CERTAIN THAT THE PUMP IS DISCONNECTED FROM THE POWER SOURCE BEFORE ATTEMPTING TO SERVICE OR REMOVE ANY COMPONENT!

1. The motor's sleeve bearings should be lubricated every six months with two to three drops of S.A.E. 20 weight non-detergent oil. The oil holes are located on top at each end of the motor.
2. All wetted parts can be serviced by removing the 4 nuts (Figure 3, item 13) which hold the volute to the housing. The pump head components can easily be replaced in the field if necessary.
3. Lightly clean any corrosion or debris which may clog the impeller.
4. If pump is tripping circuit breakers or GFCI, or not operating properly after cleaning, return it to Little Giant or its authorized service center. DO NOT attempt repairs yourself.
